Types of Drone Tethers
There are numerous varieties of drone tethers available, each with special advantages and drawbacks.
A cable tether is the most typical kind of drone tether. Cable tethers are portable, strong, and simple to set up. They give the drone a safe connection to the platform or stationary object, and they are simple to adjust to give the drone the desired range of motion.
A wireless tether is another kind of drone tether. Although there is no requirement for a direct physical connection between the drone and the stationary object or platform, wireless tethers offer the same advantages as cable tethers. Although they are typically more expensive than cable tethers, they offer more convenience and flexibility.
